How to call a Bob by its name in Perl 6?

The purpose of this example is to give you an example of the usage of the ‘name’ and ‘nameof’ operators and also the name of one particular object in Perl 6. The example illustrates a very important point: all objects in Perl 6 support the ‘name’ and ‘nameof’ operators. Every object is declared with ‘myname’, ‘mynameof’, or ‘objname’. However, all objects can accept ‘myname’ values, as well as ‘mynameof’ values, but only those values that have become part of Perl 6 by this time. If an object’s code does not provide the ‘name’ and/or ‘nameof’ operator, it will try to return an object name from the expression that called the object.

In the above example, the value ‘foo’ was used for any of the names. It would return ‘objname(foo)’ or the appropriate non-zero value.

However, ‘someobject’ has a reference to an object of type ‘bar’, and this means it’s possible to refer to that object by using ‘classname($class)’ syntax, in which the class name is prefixed with ‘a’ for example. If you refer to the name of an object by using its ‘classname’, the value is returned as $classname[‘somevalue’]. (You can also write that class name without the ‘a’ in front, in which case the value is returned as $classname[‘foo’] in the example).

Perl 6 doesn’t require that you use the ‘name’ or ‘nameof’ operators in your expression, as long as it actually returns a value, and it will not throw an error for missing an operator from the list. In most cases, there is no need to explicitly indicate how to write an expression with the ‘name’ or ‘nameof’ operators, because when you do so, all the objects in Perl 6 will do it for you.

The following table briefly summarizes the operators that you can use to access objects:

Operator Description (a, b, c) Name of a subroutine. (c $name) The value of the first (or first non-empty) property referenced by a subroutine. (d \[ $name] $value) The left operand of a reference that will result in a value, or the name of a value within the
